TAXOIDES: METABOLITOS SECUNDARIOS DEL ÁRBOL DEL TEJO (Taxus spp.)

Abstract

El árbol del tejo (Taxus spp.) es una gimnosperma dicotiledónea que pertenece a la familia Taxaceae; se distribuye en America, Europa y Asia. Taxus spp. contiene en la corteza y en las hojas, alcaloides diterpénicos conocidos como taxoides. Éstos se caracterizan químicamente por la presencia de un esqueleto de taxano y un anillo de oxetano, tal como el taxol, que es utilizado en el tratamiento del cáncer de ovario, seno, próstata y pulmón; enfermedad que actualmente es una de las principales causas de muerte a nivel mundial. El contenido de taxol es bajo en los árboles, por tanto, es necesario el uso de alternativas biotecnológicas como lo es el cultivo in vitro de tejidos vegetales para incrementar la cantidad de taxoides y preservar el recurso natural. En esta revisión científica se reportan las características químicas de los taxoides, el mecanismo de acción biológico y semisíntesis orgánica del taxol, se detalla también la ruta biosintética de los principales taxoides, así como las principales enzimas involucradas para la obtención de éstos a nivel bioquímico y, finalmente, se indica de manera general la producción de taxoides en cultivos in vitro.
